And airplanes at altitude change -370 ft over 7 minutes what was the mean change of altitude in feet per minute?

1 answer:

3 0

We have that
 [the mean change of altitude]=[change in altitude]/[time]
 [the mean change of altitude]=[-370]/[7]---------------> -52.86 ft/minute

the answer is -52.86 ft/minute (the negative sign means that the plane is descending)

Given sin theta=5/13 and cos theta=12/13, which of the following can be proven using a Pythagorean identity?

ZanzabumX [31]

Answer:

4th option

Step-by-step explanation:

given

sinΘ = $\frac{5}{13}$ and cosΘ = $\frac{12}{13}$ , then

( $\frac{5}{13}$ )² + ( $\frac{12}{13}$ )²

= $\frac{25}{169}$ + $\frac{144}{169}$

= $\frac{25+144}{169}$

= $\frac{169}{169}$

= 1

showing sin²Θ + cos²Θ = 1

A cylinder has a radius of 14 m and a height of 6 m.

oksano4ka [1.4K]

Option D: $1176 \pi \ {m}^{3}$ is the volume of the cylinder

Explanation:

Given that the cylinder has a radius of 14 m and a height of 6 m

We need to find the exact volume of the cylinder.

The formula to determine the volume of the cylinder is given by

$Volume=\pi r^{2} h$

Let us substitute $r=14$ and $h=6$ in the above formula, we have,

$Volume=\pi (14)^{2} (6)$

Squaring the terms, we get,

$Volume=\pi (196)(6)$

Multiplying we have,

$Volume=1176\pi \ m^3$

Thus, the volume of the cylinder is $1176 \pi \ {m}^{3}$

Therefore, Option D is the correct answer.
